According to the CDC's website, up to 10% of the general population has fertility problems.
So, let's take 10 million people.
1 million of them have some kind of fertility problem.
Generally speaking, 40% of fertility problems are male; 40% are female; the other 20% are either unknown, or both partners. Let's split the number and say that 10% are both partners.
Now we're down to 100,000 people.
The CDC estimates that about 85% of fertility problems can be solved without extreme medical intervention (read: IVF). So, up to 15% of those 100,000 people will try IVF.
Let's say they all go to my clinic and they're all in my age range. In which case, they have a 50-60% chance of success. We'll split the difference: 55%.
Of IVF patients, approximately 1-2% will end up with an ectopic pregnancy. Again, we'll split the difference: 1.5%.
That's 34 people.
So, today's three-part lesson is as follows:
Part one: I have an ectopic pregnancy. Damn it.
Part two: I am one of maybe 34 out of TEN FREAKING MILLION PEOPLE to whom this will happen. DAMN IT. (That is a .0000034% chance, in case you were wondering.)
Part three: I should seriously consider buying a lottery ticket.
